Column not found exception, with @ExpectedDatabase

Hey. I’m very keen on your helpful framework, thanks!

But some days ago I get the issue with @ExpectedDatabase annotation and table, names users. When I was running my tests, unexpectedly I’ve found message, that column admin can’t be found for table users. That was weird, 'cause I have not had that column neither under my entity mappings nor under expected datasets. So I’ve started a little investigation, and found, that H2 has its own table, named users as well. Here is the link with H2 information schema description: http://www.h2database.com/html/grammar.html#information_schema But, when I was doing my checks w.o. using ExpectedDatabase annotations everything went fine. I had not had any similar exceptions. So, when I was in debug, I’ve found, that table’s metadata, that populated during test indeed contained admin column from H2 own users table, and merged my table structure. So I decided to wrote a little test project to illustrate this issue, you could simple try by cloning my repository: https://github.com/vict0r81/spring-dbunit-test

Hope my description will help you to bother that kind of problem.

Thanks, Victor.

Hey!

Thanks, @sylvietseng for your solution. I’ve combined it with @FingolfinTEK latest comment and now exception I got before has gone.

So, the final solution here based on such points:

1. Updated my SpringH2Config.java with 2 beans you have provided;
2. Changed my AbstractTestBase.java in this way: from

@DbUnitConfiguration(databaseConnection = "dataSource")

to

@DbUnitConfiguration

And bingo!

Thanks, again for your help.

P.S. all updated code in my repo if anyone need it 😉 P.S.S. I believe issue can be closed.
